MMA Round Timer vs RollTimer

MMA Timer is a fast, reliable interval timer built for combat sports training. Rebuilt from the ground up in 2.0: go from launch to a running timer in two taps with Quick Start, then keep training while your phone is locked — your rounds and countdown stay live on the Lock Screen and Dynamic Island. Create sessions with blocks, rounds, rest, and optional phases inside each round (e.g., Boxing → Kicks → Clinch), or start instantly from a preset. Features • Quick Start: rounds × work × rest + one-tap format chips → GO • Interactive Live Activity — pause, resume & skip from the Lock Screen and Dynamic Island • Background-correct cues that fire on time when locked or pocketed • Real boxing bell plus synthesized cues, with distinct phase-change and round-end sounds • Phases inside rounds with a clear animated active-phase indicator • Wall-clock timing with zero drift and a color-coded draining ring • Final-10-second pulse and flash warning • Drag & drop to build and reorder sessions and blocks • Session history to track completed workouts Whether you're doing pads, bag work, wrestling, BJJ flow rounds, or conditioning, MMA Timer keeps the clock simple and reliable.

Roll Timer is a simple BJJ interval timer for rounds, rest, and sparring sessions. Set your rolls and durations, then see the estimated finish time for the full session before you start.
